Modle no. 60ESL71C Serial no. J3490074 I dont know the year or hp I assume 60hp anyway runs great just that at full throttle its like I hit a stump every few minutes the motor jumps real bad it has a electric shift and I changed the lower unit oil to a Type C for electric shift the bumbing it feels like or sliping out of gear is real sporatic this is my first post so be kind also would like to purchase a manual if I knew which one and where to find it.
